LOL!
I found this on Idigmygarden.com. I think it's just another way to add some warmth while the seeds germinate. In this case, the writer was talking about tomato seeds.
"If you have an older oven with a pilot light, then just start your seeds in there- I do start in peat pellets and then cover the whole container in plastic wrap, pop into the oven and then just check them each and every day till they sprout then I take them out and take the plastic off. I find that warmth really does help.
If your newer oven has a light bulb, keeping it on will warm the oven well too.
Just don't forget to take them if you're gonna make dinner in the oven!"
